Step-by-step explanation:
The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.
0.2 inches
4.5 inches
46.1 inches
414.7 inches
Answer:
Width of the rectangular prism
It is given to us that the volume of the rectangular prism is calculated by the given formula :-
v = lwh
Where,
v = volume
l = length
w = width
h = height
Now,
In the question we are given :-
v = 138.24 cubic inches
h = 9.6 inches
l = 3.2 inches
w = ?
Substitute these values in the volume formula given :-
138.24 = 3.2 * w * 9.6
138.24 = 30.72 * w
w = 138.24/30.72
w = 4.5
⇒ The width of the rectangular prism is 4.5 inches.
The required width of the rectangular prism is 4.5 inches.
Given information:
The volume of the rectangular prism is defined as,
[tex]V=lwh[/tex]
where l is the length, w is the width, and h is the height of the prism.
The volume of the prism is 138.24 cubic inches.
The height of the prism is 9.6 inches, and the length of the prism is 3.2 inches.
So, the width of the prism can be calculated as,
[tex]V=lwh\\138.24 =3.2\times w\times 9.6\\138.24 =30.72\times w\\w=\dfrac{138.24}{30.72}\\w=4.5\rm \; inch[/tex]
Therefore, the required width of the rectangular prism is 4.5 inches.

Jada, Diego, and Elena each use the same spinner that has 4 sections marked A, B, C , and D. Which estimate do you think is most accurate? Jada says, "The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times. " Diego says, "The probability of spinning B is 20% because I spun 5 times, and it landed on B twice." Elena says, "The probability of spinning B is 2/7 because I spun 7 times, and it landed on B twice."
Answer:
The correct option is;
"The probability of spinning B is 0.3 because I spun 10 times, and it landed on B 3 times."
Step-by-step explanation:
Out of the three trials, Jada had the most number of trials (10) and therefore, the highest precision value and the best estimate out of the three persons that did the trials
The more the sample or trials increase, the more the precision increases as the number of trial comparisons and testing increases.
The increased trials give more information, resulting in a more precise estimate. It also increases the confidence in the result and reduces the amount of uncertainty and increases precision of the results.

I WILL GIVE BRAINLIEST PLEASE HELP QUICK!!!!!!!!!!! To the nearest minute, how much time could Robert save on a 60 mile trip if he drove at 70 mph rather than at 50 mph?
Answer:
12 minutes
Step-by-step explanation:
Given the question :
how much time could Robert save on a 60 mile trip if he drove at 70 mph rather than at 50 mph?
Time taken to cover 60 miles at a speed of 50 miles per hour
Recall :
Time taken = distance / speed
Hence, at Speed = 50 mph
Time taken = 60/50
Time taken = 1.2 hours = (1.2 * 60) = 72 minutes
At speed = 70mph
Time taken = 70/50
Time taken = 1.4 hours = (1.4 * 60) = 84 minutes
Time saved :
(84 - 72) = 12 minutes

Suppose that the total annual consumption of salmon in a certain country is given by y = 5.59x + 837.5 and that the total annual consumption of tuna in this country is given by y = 1.49x + 878.5, where consumption is measured in millions of pounds and x is the number of years since 2010. When consumption of salmon reaches consumption of tuna, what is the annual consumption of salmon? 897.87 million pounds 890.42 million pounds 894.89 million pounds 893.4 million pounds
Answer:
893.4 million pounds
Step-by-step explanation:
Total annual consumption of salmon is given by [tex]y=5.59x+837.5[/tex]
Total annual consumption of tuna is given by [tex]y=1.49x+878.5[/tex]
As consumption of salmon is equal to the consumption of tuna,
[tex]5.59x+837.5=1.49x+878.5\\5.59x-1.49x=878.5-837.5\\4.1x=41\\x=\frac{41}{4.1}\\ x=10[/tex]
Put [tex]x=10[/tex] in [tex]y=5.59x+837.5[/tex] to find total annual consumption of salmon.
Therefore,
Total annual consumption of salmon = [tex]5.59(10)+837.5=893.4[/tex] million pounds

the ski team needs new uniforms. The students plan to sell plush toy eagles (the school mascot) for $5 each. The students find three companies online that sell stuffed mascots. Company A sells 18 eagles for $49.32. Company B seels 16 eagles for $43.36. Company C charges $41.55 for 15 eagles. Which company has the best to buy?
Answer:
Step-by-step explanation:
Company A = 18 eagles for $49.32
Price per eagle = $49.32 / 18
= $2.74
Company B = 16 eagles for $43.36
Price per eagle = $43.36 / 16 eagles
= $2.71
Company C = $41.55 for 15 eagles
Price per eagle = $41.55 / 15 eagles
= $2.77
The company which has the best buy is company C, they sell 1 eagle for $2.77 (highest selling price among the three companies)

A plane flies 1890 km in 3.5 hours. How far will the plane fly in 4.2 hours if it maintains the same air speed?
Answer:
2267 km
Step-by-step explanation:
1890 km/3.5 hours = 2267 km/4.2 hours
2268 km far will the plane fly in 4.2 hours if it maintains the same air speed.
How far will the plane fly in 4.2 hours if it maintains the same air speed?
The formula speed = distance ÷ time can be rearranged like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.
Given,a plane flies 1890 km in 3.5 hours.
So, distance = 1890 km and time = 3.5 hours.
We know,
Distance = Speed × Time
For example, If speed of a car is 20 m/s and the car travel 60 s then the car cover total distance
[tex]= 20 \times 60 = 1200 \: m[/tex]
Again
[tex]speed = \frac{distance}{time}[/tex]
According to question,
Speed
[tex] = \frac{distance}{time} \\ = \frac{1890}{3.5} \\ = 540 [/tex]
So, speed of the plane is 540 km/hour.
Again given time is 4.2 hours
So, Distance = Speed × Time
[tex] = 540 \times 4.2 \\ = 2268 \: km[/tex]
